USING THE 405SX

MENU FUNCTIONS

Depth Alarm. The 405SX contains an audible alarm to warn you of shallow water depths. The alarm is adjustable to depths of 2' to 99'. When the alarm is enabled, an audible alarm sounds if the water beneath the boat is equal to or less than the selected alarm depth. The alarm sounds continuously for about five seconds, and then intermittently to remind you that you are still in shallow water. Additionally, the 405SX can anticipate quickly changing terrain and sound the Depth Alarm before the bottom depth actually reaches the preset alarm depth.

Fish Alarm. The Fish Alarm alerts you to the presence of fish, or other targets not connected to the bottom. The Fish Alarm has three different settings that correspond to the three different size fish symbols shown on-screen.

The default setting is “OFF.” With the “Large fish only” setting, the 405SX alarms on only those targets that are represented by the large fish symbols. The 405SX can be set to alarm on only large and medium fish, or set to alarm on all fish.

Once the Fish Alarm is enabled, the 405SX emits an audible beep when the selected size fish symbol appears on-screen.

Fish Alarm settings are remembered when the unit is powered off.
